Yeah there are quite some traps In the hifi scene for sure
I know there is a huge discussion around jitter and it’s audibility, my hope was that a decent entry level osci is already capable of measuring into the realm of the disputable jitter second fractions
(so I can check what shielding and noise filters etc. are improving the jitter, even if it’s not audible. Just because these would be just further design questions of the dac and it’s psu, with no real costs involved. Proper design is nice to have
If I can for example check that there is no difference between a smps and my diy psu i can save some money on the choke, if not I might get one choke for the psu and if this is better than my Psu with filter caps I might get another choke just for the heck of having a really nice jitter free dac build by myself.
Edit: evening lecture now are whitepapers on jitter audibility, thanks
Edit2: just saw the jitter specs of the board I use (typical usb to i2s converters in similar range of product quality have similar given specs) are in the <5ps range. If that’s true I guess no entry level oscilloscope will be able to measure this? (On the pro side it’s probably not necessary either ^^)
